V70 fuel leak
Hi all, I have a leak when filling the car up, I have found the source which appears to be the filler pipe to tank rubber connector. Problem is I cannot see an easy way to remove the old one and put the new one on. I think the best way will be to drop the tank a little to gain access from the inspection hole above. Can anyone give me a few pointers on dropping the tank 50mm? Its a 2001 V70 T5 2WD

I've only seen 3 tanks come down in my life and all 3 were complete removals.
I suggest you drill out the right rear fender liner plastic's pop rivets. They're plastic too and come out real easily. I did this to track down an EVAP leak so I know it's easy to do. With the liner removed you be able to see the entire filler neck. There have been reports of a grounding strap wrapped around the neck such that a hole was worn through the filler neck. Just have replacement rivets and a pop-rivet gun before you start. |

Thanks for the reply. The inner wheel arch lining is already out. I can see the whole filler neck and also the leak, its at the tank end, the rubber sleeve that connects filler neck to tank. Problem is access is so tight I cant get at the clips holding the rubber part on! I was thinking drop the tank a little so I could get at part through the hole under the rear seat but I have no idea whats involved in freeing up the tank?

Not sure what if any difference there would be between your car and a P1 but for what it's worth Haynes say to remove a circlip holding the filler neck to the car then release filler neck and seals from their locations.Supporting the tank the retaining straps are undone and the tank lowered.Whether or not for your purposes you'd need to release the electrics to fuel pump/sender etc before starting the under car operations I don't know but it may be as well to do so.Goes without saying fuel tank needs to be as empty as possible and battery may be better disconnected.HTH.

I had to replace mine a few years ago. Having decided I couldn't be bothered to struggle with it on the drive, I took it to a local garage where I watched 2 guys struggle for an hour and a half on the ramps! Eventually, they supported the sub frame on a transmission jack and dropped the rear end a bit to get access.

Im hoping I only have to drop it 50mm so I shouldnt even have to mess about with the exhaust. Hopfully its not too different from the p1 description.... did you have to replace the pipe or the whole tank?
